I mean, I put them through the dishwasher sometimes anyway, but I’m told I shouldn’t? 🤷🏻♀️

The heat isn’t the issue, the detergent is. Ceramic absorbs water very easily, including the detergent. But detergent isn’t fit for consumption, yet it would leech out into your drink.
It isn’t about the heat but about the moisture. Ceramic isn’t fully waterproof and the water will sit in the pores of the material. Over time this will make the mug crack.
I took 4 quarters of ceramics in college. I absolutely loved it. Our instructor made sure all glazes were dishwasher and microwave safe. And did not allow any glaze that was not to be fired with students projects.
I can’t imagine many others doing differently.
the whole ceramic piece has to be glazed all over, or the water issues others mentioned with be a problem
It’s not the ceramic that you risk breaking, but rather the finish that is of concern. Putting delicate paints and finishes in the dishwasher is all but guaranteed to scratch and ruin their costing.
